Type 420 Stainless Steel is a martensitic grade providing both outstanding corrosion resistance and exceptional wear resistance. Typical applications include fine cutlery,machine knives, surgical instruments,wear plates, cutting tools and automotive springs.
We stock it in a range of thickness’s from 0.10mm to 3.00mm thick in strip and coil. Our stock is hardened and tempered and suitable for flat springs and blades. We can offer a cutting or profiling service.
The hardness on our stock material is normally in the range of 48/52 HRC.
